Prefabricated Houses in Linhe

There are mainly two common types of prefabricated houses in Linhe: Linhe hoisted houses and Linhe quick-assembly houses. The Linhe Operation and Maintenance Section of the Hohhot Railway Bureau Group Company once had an unsuccessful procurement of cement prefabricated houses.

Linhe Hoisted Houses: These houses adopt prefabricated construction technology. Modules are prefabricated in factories and then transported to the site for rapid assembly through hoisting. The modules are mostly made of lightweight and high-strength materials, such as cold-formed thin-walled steel, engineered wood, and composite panels. These materials have moisture resistance and controllable deformation characteristics, effectively addressing the issue of high humidity in the Linhe environment. During construction, the on-site work cycle is significantly shortened. Traditional construction processes such as foundation excavation and masonry are simplified, reducing the disturbance to the soil along the riverbank and minimizing damage to the surrounding ecological environment. Module connections mainly rely on high-strength bolts and welded joints, ensuring structural stability. Additionally, adjustable supports are equipped to adapt to possible micro-topographic changes in the Linhe area, ensuring the stability of the houses.

Linhe Quick-Assembly Houses: These are temporary or semi-professional residential units quickly assembled from prefabricated components. The main parts, such as walls and roofs, are standardized and produced in factories. After being transported to the site, they are assembled through dry construction methods such as bolt connections, resulting in fast construction speed and high efficiency. In terms of material composition, they usually adopt light steel frame structures and composite insulation panels. The light steel keels, as the main load-bearing structures, have anti-corrosion coatings that can adapt to the humidity conditions of the Linhe environment, preventing steel from rusting and corrosion and extending the service life of the houses. The enclosure structures mostly use sandwich panels, with polyurethane or rock wool fillers in the middle layer providing good thermal insulation and heat insulation functions, offering a comfortable indoor environment for occupants.

Cement Prefabricated Houses of the Linhe Operation and Maintenance Section of the Hohhot Railway Bureau Group Company: A public inquiry procurement announcement was once issued, but since only one merchant registered, which did not meet the procurement conditions, the procurement project was ultimately terminated.
